+//
+// Module 4 Assignment Instructions.
+//
+// The idea of this assignment is to take an existing array of names
+// and then output either Hello 'Name' or Good Bye 'Name' to the console.
+// The program should say "Hello" to any name except names that start with a "J"
+// or "j", otherwise, the program should say "Good Bye". So, the final output
+// on the console should look like this:
+/*
+Hello Yaakov
+Good Bye John
+Good Bye Jen
+Good Bye Jason
+Hello Paul
+Hello Frank
+Hello Larry
+Hello Paula
+Hello Laura
+Good Bye Jim
+
+WARNING!!! WARNING!!!
+The code does NOT currently work! It is YOUR job to make it work
+as described in the requirements and the steps in order to complete this
+assignment.
